'ER-ASURE-RECEIVING ATTACHMENT FOR TYPEWRITERS.

To all whom it may concern.

Be it known that I, EnwAnn K. McNnn.. a citizen of the United States, residing at Forestville, in the county of Chautauqua and State of New York, have invented a new and useful improvement in Erasure-Receiving Attachments for Typewriters, of which the following is a specification.

This invention relates to erasure receptacles for use in connection with typewriting machines. I

It is well known that much damage is done to typewriting machines due to the fact that particles of grit, rubber, paper. glass or other substances, (these particles being herein referred to as erasures) drop on various parts of the machine, as a result of erasing parts of the work, and find their way into bearings or other parts of the machine, Where they cause excessive wear. Erasure shields have heretofore been supplied with parts adapted to collect the eras-- ures, but these shields were always made de tached from the machine and would readily become lost or mislaid, or would not be used by an operator since it requires some time to find and to place these shields in position on the Work.

,The objects of this invention are to pro- Vide an erasure receptacle that can be at tached to the machine in a position to receive the erasures, thereby eliminating the delay incident to using receptacles which cannot be attached-tea machine; also to provide anerasurc receiving attachment for typewriters which can be readily attached to a machine and detached therefrom for removing the erasures accumulatcd therein; also to provide an erasure receiving attachment of this kind which has the usual scale formed thereon, to enable an operator to readily position papers or other work on the machine; also to improve the construction of devices of this kind in other respects hereinafter specified.

In the accompanying drawings, Figs. 1 and 2 are a fragmentary front elevation and v a top plan view respectively of a typewriting machine having erasure receiving attachments embodying my mvention mounted thereon.

Fig. 12 is a fragmentary perspective view of another nn .iificd form of erasure receiving attachn'ient applied to another model of typewriter.

in order to prevent the. erasures dropping into the mechanism of typewriting machines, l have provided a receptacle which is mounted on the typewriter while the sauna is in use and. in which the erasures are caught and accumulate and which can be ei'npticd. For this purpose the receptacle is constructed so that it can be quickly attached to and detached from the typewriter and held in position thereon so that all the erasures made are caught by the receptacle before they have a chance to drop into the working mechanism of the machine.

in the embodiment of my invention shown in Figs. 1 to (3, an erasure receptacle is provided which may be attached to typewriting machines of the Underwood type. having a platen A, ribbon spools B, a type guide (l and a part of a ribbon vibrating mechanism i). F represents the usual guide segment for the type bars. which is provided with a plurality of slots (2 in which the pivoted ends of thetype bars operate.

As illustrated in Figs. 1 to 6, the typewriter attachment con'ipriscs a trough i5 which is preferably formed or stamped oi sheet metal and in the-construction shown is substantially V-shaped in cross section,

having a front wall 16 and a rear wall 17. The ends of the trough may he closed by means of end walls 18 and 12), which extend laterally from a depending flange .20, which is formed by bending; the metal along the line 21 shown in Fig. 6, forming a bent rear edge at the upper rear portion of the trough. The side walls 18 and 1.9 in addition to closing l'he ends of the front and rear walls of receptacle alsorein'force the receptacle in such a manner as to prevent heading of the same about the rear edge 21. The flange is provided at one side thereof with a downwardly extending portion 2 which adapted to slidahly engage a holder or socket 25 secured on the frame of the typewriting' machine. This socket may he of any suitable or desired constructiom that sl'iown including a plate having ears or projections 26 which are bent o r turned over in a direction parallel to the plate and spaced at a distance thcrefron'i so as to permit the insertion of the downwardly er;- tending; portion 22 on the receptacle. The socket memher or bracket 25 isprovided the lower portion thereof with holes or perforations 27 through which screws 28 may pass into the segment l l for holding the socket in place. These screws are ordinarily employed for holding the scales shown in Figs. 74) in their operative positions on the machine. and in order to apply my erasure receptacles to the machine. the scales are removed and the supporting; hraclcets secured the n'mchine in place of the l by means of tho screws 28. the holes n the brackets being of larger size than the screws so as to permit adjustment of tho brackets. The erasure rcceptaclcs arc thcn lv held on the hrachets by means of r cars 26 thereof and wl'icnevcr the rcc 'otscles are fi led with crasurcs it is only necessary to pull them upwardly out of lcngagement with the brackets and empty them. whereupon they can he replaced on the orackelis.

in order to cnahlc an operator to rcadily position a. piece or work in the machine, the upper cdgrcs 21 of the erasure receptacles are positioned at the same elevation as the scales ordinarly used on the machine. and ii desircd. raduations 30 may he placed on the inner and visible face of the rear wall of the receptacles adjacent to the upper edge El thereof. When provided with these gzradual'ions the rcccptncles lake the placeoi the usual scales supplied with the llnderwood machine.

'lhe downwardly extending flange 20 and tile extension 22 thereof. or tile brackets 25 or both. are prc'lcral'ily made oi resilient mm tcrial. so. that the upper edge 21. o? each erasure receptacle is yiclding'ly ainst the our l; on the. platen. fhis enlee the erasure receptacles to receive all pressc d of the erasures and also enables the receptacles to readily adapt themselves for different thicknesses of Work placed in. the typewriter. The receptacles may be made of any suitable or desired shape to best adapt themselves to the machines on which they are used. and for this purpose the outside walls 19 thereof are. curved as shown in Fi 2 to clear the ribbon spools B and still cxtend along the platen as far as possible.

In the construction shown in Figs. '2' to 9, an erasure receiving attachment is provided which can he held on an Underwood typewriter by means of the usual scales F of the machine. With this construction it is not necessary to remove the scales from the machine as in the constructions shown in Figs. 1 to 6, and the spring 7 of the scale serves to hold the receptacle yieldingly against the platen. represents the trough. which may he of any suitable or desired construction and which has on the rear Wall thereof a downwardly turned lip or flange 33, which is adapted to slip over the upper cdgze of the scale F and thus hold the reccptacle in place. In order to take the place of the graduations on the scale, the inner face of the rear wall of the receptacle is provided with graduaiions 34. This rcccptaclc can be easily removed from the upper edsoi the scale for emptying and can hc easily n placed thereon.

lhe erasure receiving attachment shown in Figs. 10 and 11 is adapted for use on another type of machine. and in this case a soaps. is mounted on one cnd oi an arm 36. The other cud oi the arm is mounted on a clip or hraclcct 37 which may he hookcd ovcr or otherwise suitably secured to a rib hon casing B. A coil spring" 38 engages the arm 536 and the clip 3! and is adapted to norn'uilly force the arm. into the position shown in dottcd lines in Fig: 10. A second coil spring 40 is provided adjacent to the pivot connecting the other end of the arm 36 and the receptacle 35 and this spring is adapted to normally force the receptacle into a position in which the side thereof is torccd against the shoulder 41 of the arm, sce particularly Fig. 11, in which position the receptacle is held suhstantially parallel to the typewriter platen while out of engagement therewith, asshown in dotted lines in Fig. 10. In using the receptacle shown in Figs. l0 and l1; the receptacle is moved into an operative position relatively tothe p atcn by moving the outer end of the arm 36 toward the platen so that the rear edge of the trough carried on the end thereof rests flatly against the paper supported on the platen. as illustrated in full lines in Fig. 10. When the erasure has been made, the receptacle is released by the operator and then automatically returns to its normal position, shown in dotted lines-in 10,

tilled, the clip meeoee due to the action of the springs 38 and 40. The clip 37 is made readily removable from the ribbon casing, preferably by providing the same with a flange somewhat similar to the lip or llange 33), engaging the Ripper edge of the ribbon casing and when the receptacle is moved out of engagcment with the ribbon casing so that the receptacle ran. be removed from the machine and emptied, whereupon the clip can readily be replaced on the ribbon casing.

In Fig. 12 another form of receptacle is illustrated, which comprises a shallow trough 4-2 conforming in outline to the top of the frame G of the typewriter to which it is attached. The inner end of the trough is slightly turned up, as illustrated at 43, and the lower end of the trough has an additional channel 4-4 formed thereon, in which the erasures finally collect after dropping upon the receptacle. This form of receptacle is adapted to he supported below the platen and not in front of the same. are the rece 'itacles illustrated in the other ligures. In order to hold the recei'itacle shown in Fig. 12 on the machine, a clip 4-5 is f rmed on the outer end thereof. which clip is adapted to slide over an edge of the frame to yieldingtr hold the receptacle in its operative position. The clip can be readily disengaged from the machine by/forc ing it out of engagement withthe edge of the frame thereof. so that the entire receptacle can be withdrawn from under the platen and the erasures collected therein emptied.

The erasure rm'eptarh-s are all described as made of sheet metal, but it will be under stood that they may be made ol any other malerial. All of the I'P(Z(:]')l'2LCl(*.S described are mounted on the typewriter so that they a re always in a position to be readily used and remain n lhe nnu-hine while the Same is us d for writing. lonsequently if it becomes necessary to use an eraser. the collecting ol' eras tures to avoid their dropping into the parts of the machine Where they may do damage. does not involve any loss of time or extra Mi'ort on the part of the operator. The erasure receiving attachments are all so constructed that they can be easily ren'ioved from the machines for emptying the same and can be easily replaced.
